f DUMPINGr-TRUCK.

To all whom it may concern:

Be it known that I, WILLIAM H. HUNT, a citizen of t-he United States,and residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Dumping-Trucks, of which the following is a specification, such as will enablethose skilled in the art to which it appert-ains to make and use thesame.

This invention relates to dumping trucks;

land the object thereof is to provide an improved device of this classparticularly designed for hauling or transporting and dumping coal,bricks, dirt, mortar or other material or substances.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which- Figure l is a side view of a dumpingtruck involving my invention, part of the construction being brokenaway, Fig. 2 a side view of a dumping truck showing a modiication of myinvention, Fig. 3 a partial section on the line 3 3 of Fig. 2.

ln the practice of my invention as shown in Fig. l, I provide a dumpingtruck or vehicle comprising a truck frame or, and the usual runninggear, the ruiming gear with the exceptions of the front wheels a2 andrear wheels a3 being not shown or indicated.

The truck frame a is provided rearwardly of the front wheels a2 with aU-shaped raised portion a4 forwardly of which is placed a body memberZ), the back wall b2 of which is inclined upwardly and backwardly andprovided with a door o3 hinged at the bottom b4 and adapted to openbackwardly and downwardly as indicated by the arrow b5, and the bottomportion of the body member b is preferably inclined upwardly andforwardly as shown at 6G.

The door 3 may be provided with any preferred means for holding itclosed, and by opening said door the contents of the body member o maybe dumped backwardly and downwardly as will be readily'understood. l

Beneath the central portion of the truck frame is mounted a transverseshaft o having a gear wheel o2 at one end, and rearwardly of the shaft oand parallel therewith is another shaft o3 provided with a pinion o4Specification of Letters Patent.

4which meshes with the wheel o2, and said shaft 03 is also provided witha gear wheel o5, and rearwardly of the shaft o3 is a crank shaft c6provided with a pinion o7 which meshes with the gear wheel o5, and thesaid shaft o is provided with a crank o8 by which it may be turned, anda pawl o9 is pivoted to the truck frame above the pinion c7 and adaptedto operate in connection therewith so as to prevent the backwardmovement of the shaft c6.

On the rear portion of the truck frame is placed a bed or body member(Z, the rear end part of which is preferably inclined upwardly andbackwardly as shown at cl2, and the side bars a5 of the truck frame areeX- tended backwardly and downwardly and provided with upwardly curvedhook members a6, and the rear end portion of the bed or body member ciis provided with rollers a7 adapted to travel on the side bars a5 of thetruck frame as will be readily understood and to rest in the hooks a6.

Pivoted to the truck frame at as and at the opposite sides thereof aredouble diamond-shaped lazy-tongs c, only one of which is shown, and themembers of which have top and bottom connection e2 and e3, and the topmember of which has lateral connections et, and the bottom member ofwhich is provided with lateral connections c, and said lazy-tongs arealso pivotally connected at e2 with the bed or body member (l, and therea-r pivotal connections at o4, and the front pivotal connections atc5, and the pivotal connections at e3 are provided with rollers aroundwhich are passed cables c, but one of which is shown, and the cables oare connected with the pivotal lazy-tongss front connections at o4 andpassed around rollers at the rear pivotal connections e4, and thenforwardly and around the rollers at the front pivotal connections at o,and then downwardly and backwardly around the rollers at a8, and thenforwardly and secured to the shaft o, and another cable c7 is connectedwith the shaft o and passed around a roller es supported in the truckframe at the front of the body member d, and said cable e7 is connectedwith the front end portion of the body member d at e9.

lt will be understood from the foregoing description that the lazy-tongso and the cables e6 are duplicated at the opposite side of the bodymember d, and but one of the cables c7 is necessarily employed,\but twomay be employed if desired, lin which event lne gill be at each side ofthe body mem- In the operation of this form of construction, in order todump the contents of the body member d, the shaft c is turned to theright by means of the crank o8. In this operation the lazy-tongs e atthe opposite sides of the body member d are raised and the cable e7 isunwound from the shaft o.

The rear end portion of the body member (l is heavier than the front endportion, or that'portion forwardly of the pivotal connection at a8 ofthe lazy-tongs, and as the body memberd is raisedy it also movesbackwardly, the rollers a? riding on the rear end portions of the sidebars a5 of the truck frame, and in the same operation said rollers movedownwardly into the hook members a6, and the bed or body member Z as-.

sumes the position shown in dotted lines and the contents thereof aredumped as will be readily understood.

In order to return the bed or body member Z to the position shown infull lines in Fig. l, the pawl 09 is raised and the shaft 06 is turnedin ythe opposite direction, and in this operation the lazy-tongs e aregradually returned to their normal position as the cable c7 draws thebody member d back into its normal position, or that shownA in fulllines in Fig. l.

It will be understood that the cables e@ and e7 are wound in oppositedirections on the shaft c, and the construction shown in Fig. 2 is thevsame as that shown in Fig. l except that but one body d3 is employed andthe winding mechanism which operates the lazy-tongs e is placed forwardof the position shown in Fig. 1, the bed or frame-work of the truck ishorizontal and is not provided with the upwardly directed U-shaped partat shown in Fig. 1,and the lazy-tongs connection with the bed or body Z3at e2 is made as shown in Fig. 3, by means of-a plate f having anoutwardly directed pin f2 which forms the pivot for the lazy-tongs andis provided with a cotter pin f3, and by means of this construction thelazy-tongs Ymay be disconnected from the body Z3 and said body may belifted bodily from the truck whenever'desired and for any purpose, andthe top part of the body d3 is provided lat opposite ends thereof withrings, eyes or apertures f4 which will serve as connections for asuitable hoisting` apparatus by means of which the body may be raised orremoved from the truck.

Having fully describedfmy invention, what I claim as new and desire tosecure by Letters Patent, is

In a dump cart or vehicle, a truck frame the sides of which areprovidedA with. backwardly and downwardly curved extensions having hookmembers at their ends,y a bed or body mounted thereon and provided withrollers which bear on the sides of the truck frame and are adapted tomove downwardly and backwardly on said extensions and Vto rest insaidhook members, lazy-tong devices piyoted to the truck frame at theopposite sides of said bed or body and to the opposite sides of said bedor body, a winding mechanism mounted beneath the bed or body, cablesconnected with the lazy-tongs and with said winding mechanism, anothercable connected with the front end of the bed or body and passed arounda roller at the front end of the truck frame and connected with saidwinding mechanism whereby when said winding mechanism is operated in onedirection the front end portion of the bed or body will be raised andsaid bed or body moved backwardly and downwardly and turned into adumping position, and when said winding mechanism is operated in theother direction said bed or body will be turned back into its normalposition on the truck frame. n

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 11th day of March1909.

WILLIAM H. HUNT.
